Install attached file (exe) only if not already installed

[oz85]

Hello to everyone!

I searched for this topic but i didn't find out a solution. I'm a noob about advanced installer so i'm sorry for some stupid question!

I'm building a installer with a simple exe file and some custom actions based on power shell command (copy a file from a location to another and another one who create an ODBC connection). For using the ODBC connection i need a specific driver that i want to install by the main installation built with advanced installer.

The main problem is that for every version the system call the installation while i want to call this procedure only if the software is not already installed. If anyone exit the installation of driver i want to quit all the main installation.

Sorry for my english! hope someone got my point! attached some file.

Thanks!

Hello,

If the EXE that you are trying to launch through a custom action is an actual installer, I would advise adding it as a prerequisite in the "Prerequisites" page.

In that page, you can define the installation conditions so that the prerequisite (the ODBC driver) is only installed if it's not already installed. More information about this topic can be found here: Prerequisite install detection criteria - How to create one.

Regarding the main setup failing if the prerequisite is not installed, you can achieve this by unchecking the "Continue with the main installation even if the prerequisite is not installed" option from the "Installation" tab.

Thank you for the quick response!

I tried to set a Prerequisites but at a point i need to set how to install that driver. My idea is to install the driver as attachment without go to any website o to network path. But this installing need to be active only if this file is not exist.

Hello,

From what I can see, you are trying to look in the 64-bit version of the Program Files folder.

By default, this search will be redirected to Program Files (x86) if your setup is of 32-bit (you can check this in the "Install Parameters" page).

That being said, please make sure the search is marked as "64-bit" in the "Prerequisites" page --> "Condition" tab.
